Glutenite Peak-forest Landform in Qushi'an, Qinghai Province and Its Domestic Comparison Significance
-
摘要: 砂砾岩峰林地貌在地质遗迹类型划分中归到地貌景观大类-岩土体地貌类-碎屑岩地貌亚类，是地貌景观中的一大研究热点。曲什安砂砾岩峰林是高原寒、旱气候条件下形成的独特砂砾岩地貌景观，从地貌形态、形成条件、形成过程方面分析曲什安砂砾岩峰林地貌蕴含的科学内涵，并与国内砂砾岩地貌对比研究，发现曲什安砂砾岩峰林在形成时代、沉积环境、岩性、形成过程、地貌特征方面差别很大，具有较高的科研价值、美学价值和进一步开发旅游价值。Abstract: Based on the classification of geological relics, the gravel peak-forest landform belongs to the clastic geomorphic subtype of rock-soil body type in geomorphological landscape category, which serves as a major hotspot in geomorphological landscapes research. The Qushi'an peak-forest is a unique glutenite landscape formed by the cold and dry climate conditions in the plateau. The scientific connotation of this glutenite peak-forest landform has been analyzed in this paper from the aspects of topographic forms, formation conditions,and formation process. And then, this glutenite peak-forest landform has been compared with the domestic glutenite geomorphology. The results show that this glutenite peak-forest is very different from other geomorphological features in the formation age, sedimentary environment, lithological characters, formation processes and geomorphological features. Therefore, it has high scientific value, aesthetic value and tourism value for further development.
